Plate pickaxe assembly for crushing frozen materials

Abstract

The invention discloses a plate pickaxe assembly for crushing frozen materials. The plate pickaxe assembly comprises a guide rail arranged on a chute counter bore and a plate pickaxe body slidably connected to the guide rail. An upper sliding block, a lower sliding block and chip grooves are arranged on the lower surface of the plate pickaxe body, the upper sliding block and the lower sliding block are slidably connected with the guide rail, a power device is detachably connected between the upper sliding block and the lower sliding block, the chip grooves are symmetrically formed relative to the upper sliding block, two first flow guide faces are arranged at the top end of the plate pickaxe body, a plurality of ice breaking teeth are evenly arranged between the two first flow guide faces, and the first flow guide faces are obliquely arranged in the direction of the ice breaking teeth. A plurality of second flow guide faces are sequentially arranged on the upper surface of the plate pickaxe body from top to bottom, the second flow guide faces are obliquely arranged in the direction of the ice breaking teeth, and material filing teeth are arranged between every two adjacent second flow guide faces. According to the assembly, the working efficiency can be improved, and the danger of manual deicing is avoided.

Description

technical field [0001] The invention relates to the technical field of chute cleaning, in particular to a pick assembly for crushing frozen materials. Background technique [0002] In coal mines, power plants, mines, and quarry factories, material storage warehouses are essential, such as coal mines, coal bunkers in power plants, and silos in stone factories. There are many chutes with upper, lower, and smaller structures. This structure is prone to blockage, especially in the cold northwestern region, where wet muddy materials gradually freeze on the inner wall of the chute at low temperature to form a frozen wall phenomenon. When the frozen wall gradually thickens, The blanking becomes more and more difficult and slow, and finally the fluff blocks and freezes. This kind of frozen sticky wall is very strong, and it is basically ineffective to rely on manual dredging, which has seriously affected normal production. [0003] The frozen material is cleaned by hand-held elect...

AI Technical Summary

Problems solved by technology

[0004] There is a rotary cleaning machine installed to clean the frozen wall. When the machine is in continuous operation, it can continuously sweep the inner wall of the chute, which can prevent the frozen wall to a certain extent. However, if it does not operate for a period of time, the frozen wall will still If it appears, it will freeze the scraping machine together. At this time, the scraping machine cannot work normally and loses its function; by installing a hydraulic cleaning machine, the hydraulic cylinder is used to drive the rake teeth to reciprocate to clean the frozen and sticky wall materials. The strength of the rake teeth itself is not high, and it is easy to deform and fail when cleaning materials with a strong frozen wall, and the structure of the rake teeth destroys the smooth surface of the inner wall of the chute, which has an adverse effect on the flow rate of the chute, making it easier to accumulate and block If the finely divided material is stuck, the material flows more slowly, making the frozen wall more likely to occur
